Procedure

A solution of 2-(3-methoxycarbonylamino-2-oxo-piperidin-1-yl)-propionic acid (48.5 mg, 0.20 mmol), HATU (91 mg, 0.24 mmol), and 4-methylmorpholine (109 pt, 0.99 mmol) in dimethylformamide (5 mL) was stirred at ambient temperature for 5 minutes. [1-(2-{5-[4′-(2-Amino-acetyl)-biphenyl-4-yl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-2-methyl-propyl]-carbamic acid methyl ester (100 mg, 0.20 mmol) was added to the reaction mixture. After 40 minutes the solvent was removed under reduced pressure and the resulting residue was taken up in ethyl acetate (10 mL). The resulting mixture contained a solid and was subjected to flash chromatography with eluent of (10% methanol in ethyl acetate) and hexane followed by 30% methanol in DCM. The product-containing fractions were combined and the solvent was removed under reduced pressure to provide (1-{1-[2-(4′-{2-[1-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-biphenyl-4-yl)-2-oxo-ethylcarbamoyl]-ethyl}-2-oxo-piperidin-3-yl)-carbamic acid methyl ester (149 mg, 0.20 mmol, 99%). C38H47N7O8 calculated 729.4 observed [M+1]+ 730.6; rt=1.78 min.
